Publication Abstract from PubMed

In bacteria, the synthesis of the protective peptidoglycan sacculus is a dynamic process that is tightly regulated at multiple levels. Recently, the lipoprotein co-factor LpoB has been found essential for the in-vivo function of the major peptidoglycan synthase PBP1b in Enterobacteriaceae. Herein, we reveal the crystal structures of Salmonella enterica and Escherichia coli LpoB. The LpoB protein can be modeled as a ball and tether, consisting of a disordered N-terminal region, followed by a compact globular C-terminal domain. Taken together, our structural data allows us to propose a revised model for LpoB mediated regulation of peptidoglycan synthesis.
